Downtime for a 24 hrs avilable Resource

Summary: We have the requirement to put the scheduled downtime of the resources in the Supply Plan. The resources are 24 hrs available but there would be planned downtime and also if we know that the resource is not available due to breakdown, how to capture that? We tried using resource availability template but that is not working and getting error out due to the resources are marked 24 hrs available in the resource template.

Is there a way to intimate system that resources will not be available for some duration. Please note this is stand alone implementation of supply planning.
